For example, you can can rename any private directory "folder" to "rfolder" (r for restricted) and create a rule to restrict access to every virtual path that matches the pattern "/r*"._________________Support Team

I tried fill "b/b" in "Virtual Path Regular Expression" filed and tested.
It matches path "/tab/bed/".
----It seems----
Just need one part of a string matches with the given Regular Expression to make the rule TRUE.

"^/r" and "^/.*" mostly have the same mean in "Virtual Path Regular Expression" unit in Abyss Web Server.

"/r*" should works in "IP Address Control"-"Virtual Path" unit, as a Pattern to match any path start with "/r"
If fill it in "Virtual Path Regular Expression" filed, will match any "/" in any path.
-----------------
Sorry, I am unfamiliar with Regular Expression.
Here's my Regular Expression for the case in first post:
^(?!/public(?:$|/.*?)).*?$
I tested,
Hope it truly right for Abyss Web Server._________________Ah Ha!
